When I started story-mode, the game seemed very dark, like it was night. When I changed my resolution, in the background I saw this problem was fixed. But when I got back to the game, all textures were dark again. The sky is blue, but the rest of the game is all black. Can someone help me?

Have you guys checked the Validity of your files? If you don't know how to do that, Go to your library and right click Cabella's Dangerous Hunts 2013. Go to properties, Local Files, and then Verify Integrity of Game Cache..... I don't know if it will work or not, but that is all I can think of. It may have to redownload a small file that accedentally got deleted off your computer.
